compare the expressions
3 X 10 and 15 x 20 without multiplying them. Explain how she
could compare the factors to compare the expressions without
multiplying them.

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

Well 3 is a factor of 15, and 10 a factor of 20. So 15/3 is 5, and 20/10 is 2.

5*2 is 10, which means that 15*20 is 10 times greater than 3*10.

If you actually did multiply them, 15 by 20 is 300 and 3 by 10 is 30. It would logically be correct.

Answers

Answer

I guess so.

To find the LCM you need to know the lowest digit as possible.

For example,

Question: What is the LCM of 8 and 6?

Answer: Table of 8: 8, 16, 24, 32, 40,48

             Table of 6: 6, 12, 18, 24, 30, 36, 42, 48

Now look at the tables again and, did you see the LCM???......

If so your answer would be 24.

Algebra 2 Need help with b

Answers

Answer:

a. was incorrect a = -0.109569028 so...

y = -0.109569028(x + 7)² + 54

b. It's been the above vertex equation for a parabola then

set y = 40 equal to the parabolic equation, we get

40 = -0.109569028x² - 1.533966392x + 48.631117628

solve for x we get

x = -18.3036867393939 or ~ 18.3 feet

Step-by-step explanation:

y = a(x - h)² + k

(h, k) = vertex = (-7, 54)

x = h is the axis of symmetry -7

y = a(x -(-7))² + 54

y = a(x + 7)² + 54

solve for a by inputting the point (15.2, 0)

0 = a(15.2 + 7)² + 54

-54 = a(22.2)²

-54 = 492.84a

a = -54/492.84

a = -0.109569028

Answer:

The vertical change is 1

The horizontal change is =2

The rate of change  .5

Step-by-step explanation:

Point A is at (2,1)

Point B is at (4,2)

The vertical( up and down) change is (2-1) = 1

The horizontal ( left and right) change is (4-2) =2

The rate of change is vertical over horizontal (1/2) = .5

Right triangle CDE has its right angle at vertex
D. The length of DE is 8 feet and the length of
CE is 17 feet. What is the length, in feet, of CD?
A) 11
B) 12
C) 14
D) 15

Answers

The answer is A 11 feet

The length of the side CD which is the base of the right triangle CDE is 15 feet which is option D.

We have,

We can use the Pythagorean theorem to solve for the length of the height CD in the right triangle CDE.

Where CE is the hypotenuse and De is the base.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we have:

CD² + DE² = CE²

Plugging in the given lengths:

CD² + 8² = 17²

CD² + 64 = 289

CD² = 289 - 64

CD² = 225

CD = √225

CD = √15²

CD = 15

Thus,

The length of the side CD which is the base of the right triangle CDE is D. 15 feet.

[tex]\frac{5}{6}[/tex]

Step-by-step explanation:

Hi there!

We are given the following expression:

[tex]\frac{1}{6}[/tex] ÷[tex]\frac{1}{5}[/tex]

And we would like to solve it

Whenever we are dividing fractions, we are actually multiplying the first fraction (in this case, 1/6) by the reciprocal of the second fraction (in this case, 1/5), which is the "flipped" version of that fraction; the value that is in the numerator becomes the value in the denominator, and the value in the denominator becomes the value in the numerator.

So the reciprocal of 1/5 is 5/1, or 5/1

So we will multiply 1/6 by 5

[tex]\frac{1}{6} * 5 = \frac{5}{6}[/tex]

The fraction is in the simplest form; 5/6 is the answer.

Hope this helps!

1/6 divided by 1/5
When dividing fractions we keep the first fraction the same , change the sign to multiplication and flip second fraction. Some teachers use KCF (keep change flip) as a way for students to remember .
So let’s do it :
1/6 x 5/1 = 5/6
Your answer is 5/6

Find the value of y' when x
O if
xy^8 + e^y/5 =
= e.

Answers

It looks like the given equation says

[tex]xy^8 + e^{y/5} = e[/tex]

When x = 0, you have

[tex]0\cdot y^8 + e^{y/5} = e \\\\ e^{y/5} = e^1 \\\\ \dfrac y5 = 1 \\\\ y=5[/tex]

Differentiating both sides with respect to x gives

[tex]\left(xy^8 + e^{y/5}\right)' = e' \\\\ \left(xy^8\right)' + \left(e^{y/5}\right)' = 0 \\\\ x\left(y^8\right)' + x'y^8 + e^{y/5}\left(\dfrac y5\right)' = 0 \\\\ 8xy^7y' + y^8 + \dfrac15e^{y/5}y' = 0[/tex]

That is, the derivative operator distributes over sums, and the derivative of a constant is 0; apply the product rule on the first term and chain rule on the second; then use chain rule one more time.

Now plug in x = 0 and y = 5, and solve for y' :

[tex]8\cdot0\cdot5^7y' + 5^8 + \dfrac15e^{5/5}y' = 0 \\\\ 5^8 + \dfrac15e y' = 0 \\\\ \dfrac15e y' = -5^8 \\\\ y' = \boxed{-\dfrac{5^9}e}[/tex]
